STRlKING-BAG PLATFORM.

. SPECIFICATION forming part of Letters Patent No. 780,784, dated January 24, 1905.

Application filed April 7, 1904. Serial No. 202,036. v

To all whom it may concern.-

Be it known that I, EDWIN KIMBALL DAVIS, a citizen of the United States, residing at Philadelphia, Pennsylvania, have invented certain new and useful-Improvements in Striking-Bag Platforms, of which the following is a specification.

My invention is designed to provide a striking-bag frame of the strongest possible construction at a minimum cost.

Heretofore it has been the practice to make striking-bag disks or platforms of wood and of metal, the metal platforms being generally of tubular material and sometimes semitubular; but it has been found that the strain is so severe upon all the parts of a frame or platform of this character that the wooden frames will come apart, and metal frames, where they are bolted together, will become loosened under the constant jarring. I aim to overcome the displacement'or loosening of the parts on the one hand and to reduce the cost of the platform on the other hand, and I do this by making the parts of the frame of channeled sheet metal, and instead of bolting the parts together I use rivets.

In the accompanying drawings I have illustrated the invention, Figure 1 being a front elevation, Fig. 2 a side elevation, Fig. 3 a plan View, of my improved frame. Fig. 4 is a detail view, and Fig. 5 a modification.

The vertical frame A in the drawings may represent the wall or other support or place of attachment for the striking-bag frame proper andis not a part of my invention.

I utilize a ring B, made of channeled sheet metal, formed by the use of a die preferably,

and this receives the impact of the bag. The under surface of this ring is rounded and slightly broadened out, as in Fig. 4, thus making unnecessary the nice. adjustment of the bag so essential where a narrow impact-surface is used. I find that the channeling of the ring strengthens it very materially. The ring is braced by a Y-piece, this piece being riveted at threepoints to the ring and being in line with its upper surface, as shown at a, b, t

and c. The base 6 of the Y-piece carries at its pointof junction with the branching braces the depending bag-support d. The branching braces e are not as wide as the base a of the Y, and they extend to the supporting-frame, where they are secured by rivets passing through the turned-up ends f. The Y-piece is also made of channeled sheet metal, and thus is made capable of resisting great strain. The channeled Y-shaped piece is provided with a rounded portion at g conforming to and fitting the interior of the ring B and supports the ring at the points 7) and'c by clips or angle-irons. The low broadened surface of the ring is left free and smooth for the bag to strike against. The ring is further supported by two inclined angular braces 7t, made of channeled sheet metal, riveted at their lower ends to the ring, toward the front thereof, and converging toward each other as they extend upwardly in an inclined position to the vertical supportingframe,to which they are likewise riveted. These inclined braces, like the Y-shaped piece, are provided with extensions at the ends, which lie in the hollow of the ring, where they are out of the way.

Instead of forming the ring of channeled metal of curved form in cross-section said ring may be flat on its lower side, as shown in Fig. 5, and be provided with upwardly-extending sides to which the flat extensions of the braces are connected.

What I claim is A striking-bag frame comprising a channeled ring, a channeledbrace extending from the front of the ring across the top of the same horizontally, terminating in two diverging arms supporting the ring at two points and extending beyond the ring to a point of sup port, and two additional braces extending from the front of the ring upwardly at an angle, and converging toward the point of support whereby the ring is suitably braced, substantially as described.

In testimony whereof I aflix my signature in presence of two Witnesses.
